New Year. You can use the method demonstrated here to model the current and archived orders using TPC. 　　Compared with other inheritance mappings, TPC inheritance ing has a particularly important performance advantage. When querying a group of data types, queries are generated for the underlying database tables, without any additional join connections like The TPT inheritance ing or filtering like the TPH. This performance advantage is crucial for la

I have been building a car behind closed doors all the time.

I have been busy with projects recently and encountered a very tangled problem in the process. Other shell scripts can be called only after the shell script training database is executed. Here we will summarize and share it with you. The script is as follows: The shell script is as follows: #! /Bin/sh SQL _dir =/home/Tang/Tek/SQL/TekShell_dir =/home/Tang/Tek/SH/TekLog_dir =/home/Tang/Tek/logs ./Home/Tang/. bash_profile # $ Shell_dir/runsql. sh/home/Tang/Tek/SH/Tek/test.

reduces the compatibility. I have seen a saying that this is similar to DirectX technology in windows. The appearance of such a situation means that there must be a superhero who will save us from the fire. He is the intel virtualization technology for directed I/O (Intel VT-d) in the previous lecture ). I wanted to give up the last lecture and then I want to give up. This is a good story. Like the CPU solution, Intel VT-D technology is a hardware-aided virtualization technology based on the N

supports TPH and TPT, and is partially supported for TPC.File type: LINQ to SQL uses a Database markup Language (DBML) file that contains XML to map entity and data tables. EntityFramework uses four files. The first one is the entity Data Model (EDMX), which is used in the designer. The edmx file produced the other three files at the time of compilation. The first of the other three files is the Conceptualschema definition Language (CSDL) file, which
